Apera TN500 Portable White Light Turbidity Meter with EPA Compliant Data Logger
Product Description
The Apera TN500 Portable White Light Turbidity Meter is designed for precise turbidity measurement in drinking, ground, surface, and saline waters, as well as domestic and industrial wastewater. Utilizing a tungsten filament lamp with a 90° light scattering detection method, the device complies with the U.S. EPA 180.1 standard, ensuring accurate and reliable data critical for environmental monitoring and molecular diagnostics workflows focused on water quality.
Key technical features include:
- EPA 180.1 method compliance for regulatory-standard turbidity measurement
- White light tungsten filament lamp providing stable illumination for precise scattering analysis
- Intuitive operation system ensuring efficient field use by water quality professionals and bioprocessing specialists
- Long-term instrument reliability ideal for continuous environmental and clinical diagnostics monitoring
- Simple calibration and GLP-compliant data management facilitating traceable and reproducible measurements
- Integrated data logger supporting detailed analysis in biomanufacturing and synthetic biology applications involving aqueous solutions
The TN500 is widely adopted in environmental biotechnology, molecular diagnostics, and biomedical engineering research domains for assessing water clarity and turbidity — essential parameters in bioprocessing and gene editing workflows requiring strict water quality control. This portable turbidity meter offers a robust solution for both onsite and laboratory water quality analysis, supporting critical regulatory compliance and advanced synthetic biology applications.
